I was thinking that Conway's game of Life could be used as a "toy" 2d analog that describes the computational model for people unfamiliar with such models, and it could be far simpler and shorter than the existing material going from hypergraphs to causal graphs to multiway systems.
The point would be the following:
Now - this model isn't 3d, or multi-way branching - yet it is quite analogous to the concepts expressed in the Wolfram Model - only very simple, and very visual....There is almost no code, and lots of complex behavior.
Is using the 2d Game of Life as a toy analog for the purpose of explanation to others a useful idea?

The attached is not a Library as such. Its just a notebook playing around with the Game Of Life rule. Blinkers, Guns, Gliders etc.
When opening the notebook you will see this:
